DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, the meter pit with an upper end of one embodiment is illustrated at 21. It comprises a hollow cylindrical wall 23 having an interior space 25 with a circular bottom opening 27 and a top circular opening 29 leading to the interior 25. At the bottom, the wall 23 extends inward at 23B and then upward at 23BU defining the bottom opening 27. Two openings 41 at the bottom are formed through the structure for receiving the inlet and outlet pipes of a water meter to be located below ground level. Members 45 are break away members which are removed when the openings 41 are located to receive the meter pipe. In using the meter pit, a hole will be formed in the ground around the meter with the meter pipe located in the openings 41. The upper wall 43 of the meter pit will be located at ground level.
The upper wall structure of the meter pit of FIG. 2 has three slots 51 with the centers of adjacent slots spaced 120 degrees apart for receiving the three lugs 53 of a lid cover 55 as shown in FIGS. 6 and 7. In the embodiment of FIG. 1, the upper wall has four slots 51 with the centers of adjacent slots spaced 90 degrees apart for receiving the four lugs 53 of a lid cover as shown in FIGS. 8 and 9.
The upper structure in which the slots 51 are formed for receiving the lid cover lugs 53 and for supporting the lid cover 55 now will be described. Referring to FIGS. 3, 4, and 5, the cylindrical wall 23 has an upper circular edge 71 with a given inner diameter. An upper annular wall 73 extends radially outward from the edge 71 to an outer edge 75. An outer cylindrical wall 77 extends upward from the edge 75 to a top circular edge 79. A top annular wall 43 extends radially inward from the top edge 79 to an inner edge 83. An inner cylindrical wall 85 extends downward from the edge 83 to a level lower than the wall 73 defining the circular opening 29 which has an inside diameter less than the inner diameters of walls 23 and 77.
Each slot 51 is formed by two spaced apart side walls 91 and 93 extending inward from the inner cylindrical wall 85 to an intermediate outer wall 95 spaced inward from the wall 77. Walls 91, 93, and 95 extend downward from the wall 43 to a bottom slot wall 97 which joins the wall 85 at a level below the level of wall 43 and above the level of wall 73. Thus each slot 51 of the embodiments of FIGS. 1 and 2 extends radially outward from the wall 85 sufficient to receive the lugs 53 of a lid cover 55 as shown in FIG. 3 or the lugs 53 of a lid cover 55 as shown in FIG. 10. In the lid cover of FIG. 3, the lugs 53 are located at a greater radius from the center of the cover than the lugs of the lid cover of FIG. 10.
In one embodiment, the meter pit 21 is formed of a suitable plastic material. The walls 23, 23B, 23BU, 73, 77, 43, 85, 91, 93, 95, and 97 each have a thickness of about 3/16 of an inch. The radial distance DR of each slot 51 is 14/16 of an inch and the distance DC of each slot 51 is 16/16 inches. The outside diameters of walls 23 and 77 are 193/4 inches and 211/4 inches respectively. The inside diameter of wall 85 is 173/4 inches. The outer height of wall 77 is 1 inch. The inside heights of walls 95 and 85 are 1/2 of an inch and 11/4 inches respectively. The total height of the meter pit is 24 inches. Thus the meter pit will accept lid covers having lugs 53 with outer edges located at diameters greater than 173/4 inches and less than 181/2 inches. The lid covers 55 of FIGS. 3 and 10 will be of the type shown in FIGS. 8 and 9 for use with the meter pit of FIG. 1 and will be of the type shown in FIGS. 6 and 7 for use with the meter pit of FIG. 2.
It is to be understood that the meter pit of the invention can have dimensions different from those listed above.
As shown in FIGS. 6-9, each of the lid covers 55 comprises an annular bottom wall 101 from which the lugs 53 extend and which is coupled to a cone shaped wall 103. At the top of the cone shaped wall 103 an annular wall 105 extends inward forming a circular opening 107 and a cylindrical wall 109 extends upward for removably receiving a circular lid 111 for coveting the opening 107. The cover 55 and lid 111 may be formed of metal or plastic. When the lid cover is located on the meter pit, the annular wall 101 will rest on the wall 43 and the lugs 53 will be located in the slots 51.
